Insulation
Okoguard is Okonite's registered trade name for its exclusive
ethylene-propylene rubber (EPR) based, thermosetting compound, whose optimum
balance of electrical and physical properties is unequaled in other solid
dielectrics. Okoguard insulation, with the distinctive red color and a
totally integrated EPR system, provides the optimum balance of electrical
and physical properties for long, problem free service. The triple tandem
extrusion of the screens with the insulation provides optimum electrical
characteristics.
Jacket
The Okoseal (PVC) jacket supplied with this cable is mechanically rugged and
has excellent resistance to flame, oil,acids and most chemicals. |

Applications
Okoguard shielded Okoseal Type MV-105 power cables are recommended for use
as feeder circuits, in electric utility generating stations, for
distribution circuits, and for feeders or branch circuits in industrial and
commercial installations. Type MV cables may be installed in wet or dry
locations, indoors or outdoors (exposed to sunlight), in any raceway or
underground duct, directly buried if installed in a system with a grounding
conductor in close proximity that conforms with NEC Section 250.4(A)(5), or
messenger supported in industrial establishments and electric utilities.
Sizes 1/0 AWG and larger may also be installed in cable tray.

Available from our Customer Service Centers. Minimum Manufacturing Quantity
for non-stock items is 5000'.
Aluminum Conductors
(1) Aluminum conductors are available on special order. To
order aluminum conductors, change the first three digits of the catalog
number from 115 to 135.
Ampacities
(2) Ampacities are in accordance with Table 310.73 of the
NEC for three single Type MV-105 conductors, or single conductors twisted
together (triplexed) and installed in an isolated conduit in air at an
ambient temperature of 40°C and a conductor temperature of 105°C.
(3) Ampacities are in accordance with
Table 310.77 of the NEC for three single conductors or triplexed cable in
one underground raceway, three feet deep with a conductor temperature of
105°C, 100% Load Factor, an ambient earth temperature of 20°C, and thermal
resistance (RHO) of 90.
Refer to the NEC, IEEE/ICEA S-135 Power Cable Ampacities,
or the Okonite Engineering Data Bulletin EHB for installation in duct banks,
multiple point ground shields, other ambient temperatures, circuit
configurations or installation requirements.
(4) Ampacities based on single Type MV-105
conductors, or single conductors twisted together (triplexed, quadruplexed,
etc.) size 1/0 AWG and larger, installed in uncovered cable tray in
accordance with Section 392.13 of the NEC at an ambient temperature of 40°C
and a conductor temperate rating of 105°C. In accordance with NEC Section
392.13(b) (copper conductors), the values are 75% of the values given in
table 310.69. Where the cable tray is covered for more than six feet with
solid unventilated covers, the ampacities shall not exceed 93% of the values
shown above.
(5) Recommended size of rigid or
nonmetallic conduit for three conductors based on 40% maximum fill.
*The jam ratio, conduit I.D. to cable O.D. should be checked to avoid possible jamming.
